The Line Item Builder is a purpose-built repeatable-row field for line items — invoice lines, order rows, quote items. It looks similar to Dynamic Add/Remove but with built-in conventions for product lookup, quantity, unit price, and totals.
Conditional options
- List Item Builder (Required) — pick a Line Item Builder definition from the Architect Panel → Line Item Builders admin.
- Store data in external table? (Required) — same trade-off as Dynamic Add: separate-table for relational integrity vs. serialised for simplicity.
Why pick Line Item Builder over Dynamic Add
- Built-in row total / overall total handling.
- Sensible default columns and validation for the line-item use case.
- Cleaner UI on the rendered form.
